Hi, When doing link development between my websites, I take care to make use of different C-class IPs. Should I use different Google Analytics accounts? Same question with Google Webmaster tool? Thx
I prefer to keep everything about my sites as transparent to Google as possible. If your links between sites are related and not spammy you'll be fine with Google. If your links aren't white hat then you're probably going to need some obfuscation. But beware, Google is pretty good at finding all the sites you own. They are collecting data about your own surfing patterns when you use Google Search or if you install the toolbar. They even get a snapshot of what sites you visit from other people's analytics accounts. Then they see you hit your sites more than anything else, see you log into different analytics accounts, and on and on. Before you know it they start adding sites to the list.
That is my primary opinion on the subject. Always add value and avoid black hat. Concerning Google, is it of primary importance to host our websites under different C-class IPs?
